We’ve covered the Tiny Tapeout project a few times on these pages, and while getting your digital IC design out there onto actual silicon for a low cost is super cool, it is still somewhat limited. Now, along comes the German FMD QNC project funding MPW (multi-project wafer) runs not in bog standard Silicon CMOS but Silicon-Germanium bipolar technology. And this is accessible to you and me, of course, provided you have the skills to design in this high-speed analog technology.
The design can be submitted via Github by cloning the IHP-Open-DesignLib repo, adding your design, and issuing a pull request. If your submission passes the correctness checks and is selected, it will be fabricated in-house by the IHP pilot line facility, which means it will take at least four months to complete. However, there are a few restrictions. The design must be open source, DRC complete (obviously!) and below a somewhat limiting two square millimetres. Bonus points for selecting your project can be had for good documentation and a unique quality, i.e., they shouldn’t have too many similar designs in the project archive. Also, you don’t get to keep the silicon samples, but you may rent them for up to two years for evaluation. In fact, anybody can rent them. Still, it’s a valuable service to trial a new technique or debug a design and a great way to learn and hone a craft that is difficult to get into by traditional means. Such projects would be an excellent source of verifiable CV experience points we reckon!
